Highlights: Sum rules of order one for domains of arbitrary shape are considered. The sum rules are proved to be finite. Exact expressions for number of examples are obtained. These expressions are verified with accurate numerical tests. -- Abstract: We have derived explicit expressions for the sum rules of order one of the eigenvalues of the negative Laplacian on two dimensional domains of arbitrary shape. Taking into account the leading asymptotic behavior of these eigenvalues, as given from Weyl’s law, we show that it is possible to define sum rules that are finite, using different prescriptions. We provide the explicit expressions and test them on a number of non trivial examples, comparing the exact results with precise numerical results.
